MACHINE FOR MAKING GARDEN-RAKES.

SPECIFICATION forming part of Letters Patent Elm 226,898, dated April27, 1880.

Application filed July 19, 1879.

To all whom it may concern:

Be it known that I, GEORGE BANISTER, of Columbus, ill the county ofFranklin and State of Ohio, have invented certain new and usefulImprovements in Machines for Making Garden-Rakes; and I do herebydeclare the following to be a true and exact description thereof,adapted to enable others skilled in the art to which it pertains to makeand use it, reference being bad to the accompanying drawings, formingpart of this specification.

My invention relates to mechanism for cutting teeth in garden-rakes andforming implements analogous thereto.

. The improvement consists in the construction hereinafter described andclaimed.

Referring to the drawings, Figure 1 is a view, in side elevation, ofsuch parts of a machine as are necessary to represent the invention.Fig. 2 is a detail view of the elastic blank-holder. Fig. 3 is a plan ofthe lower stock. Fig. 4 is a reverse plan of the upper stock. Fig. 5 isa section through line S T of Fig. 4. Fig. 6 is an exhibit of a blankafter it has been operated upon.

The lower stock, A, is provided with a suitable die, B, secured theretoby a wedge, O. It is further provided with an elastic blankholder, E,which latter consists of two distinct parts, a and I), connectedtogether by a springmetal plate, 0. A transverse slot, (1, is formed inthis holder, through which passes'asuitable fastening device, U. By thismeansthe holder may be adjusted to and fro in a line which is at rightangles to the length of the blank as the latter is in position on thedie. This adjustment of the holder regulates and determines the width ofthe rake-head or other blank.

A longitudinally-tapering gage, D, is connected by tongue-and-grooveengagement with the blank-holder, and has sliding movement in the lineof its length. The upper stock, J, works up and down in a verticalguideway, (not here represented,) and is provided with a spring, Q. Thelatter consists of a springmetal bar formed with a return bend, one endof the bar being secured tothe stock and the opposite end being free.This upper stock is further providedwith a punch, P, of the desiredform, the'stem of which fits in a slot, 0. This slot communicates withan L-slot formed in the upper stock, and in which fit the twoindependent wedges N and O. Wedge O bears against the side of thepunch-stem, and wedge N bears against the endof the stem. The upperstock is also provided with dies L M, while the lower stock is providedwith counterpart dies H I. The blank is subjected to these dies, bywhich the set is made and the nipple R is drawn out. The shank whichreceives the handle is afterward welded to this nipple.

To form the teeth the blank is placed on die B in position to be clampedby holder E. On the downstroke of the upper stock the free end of springQ, bears down upon the elastic holder, and the latter is thereby causedto securely clamp the blank. After the punch has operated upon the blankthe upper stock moves on its upstroke, the spring Q is freed fromcontact with the elastic holder, and the blank is released from itsclamp. Said blank is then fed forward, the slide-gage D moving with itand imparting the proper inclination to the line of its teeth. As thepunch becomes worn away by grinding it is vertically adjusted inposition by wedge N, and is secured in such position by wedge 0.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination, with the elastic blankholder, of the device adaptedto compress the latter on the downstroke of the punch, substantially asset forth.

2. The combination, with the punch and die, of the elastic blank-holderand the spring which compresses the latter on the downstrokeof-thepunch, substantially as set forth.

3. Thecombination, with the punch and die, of the gage, made inlongitudinal tapering form for use, substantially as set forth.

GEORGE BANISTER.
